Faedah dan Kelebihan Utama
-
Unique No Bleed Monitor System: Eliminates the constant waste of gas to the atmosphere by utilizing a pilot system that bleeds 100% of the loading gas back into the downstream system, making it an environmentally friendly choice.
-
High-Capacity Pressure Control: The pilot-operated design allows for much higher flow capacities than standard direct-operated regulators of the same size, often allowing for smaller and more cost-effective installations.
-
Superior Accuracy: The high-gain pilot ensures that the outlet pressure remains extremely close to the setpoint, even as inlet pressures fluctuate or demand changes rapidly.
-
Registration Versatility: The 299H can be easily converted between internal, external, or dual pressure registration, providing the flexibility to sense pressure exactly where it is needed for the specific piping layout.
-
Integrated Safety Options:
-
Type 299HR: Includes an integral token relief valve that provides a small atmospheric discharge to alert operators if the downstream pressure increases beyond the setpoint.
-
Type 299HV: Integrated with a Type VSX8 slam-shut valve to completely stop gas flow in the event of an overpressure or underpressure condition.
-
Type 299HVR: Combines slam-shut protection with a token internal relief valve to manage minor overpressure from thermal expansion.
-
-
Easy Startup and Maintenance: Designed for simplicity in the field, the 299H allows for straightforward startup procedures. Maintenance is simplified by the ability to access internal parts without removing the regulator body from the line.
-
Rugged Construction: Built with heavy-duty materials to ensure a long service life in demanding industrial environments and outdoor utility installations.
Hartanah Teknikal
-

Bidang Aplikasi
The 299H Series is the preferred regulator for medium-pressure distribution systems and large industrial gas trains where both high capacity and tight control are required.
Industri Utama dan Kegunaan:
-
Commercial Gas Service: Large meter sets for shopping centers, schools, and hospitals.
-
Industrial Burner Systems: Fuel gas supply for high-capacity boilers and furnaces.
-
District Regulating Stations: Used by utilities for pressure reduction in neighborhood distribution loops.
-
Safety-Critical Applications: Systems requiring overpressure shutoff (OPSO) or underpressure shutoff (UPSO) protection.
